I'd love to have an EP booster, and a Klon modelled overdrive up at the front end. These are fairly simple effects, that I suspect would be useful to lots of players I'd also like a Leslie/Rotating speaker cab effect. This may not have such universal appeal,. But it would be awesome. Oh. The other thing I'd like is to be able to do is move the reverb block, so I can put it before a tremolo, and get the 'how soon is now' tone. I doubt that one will happen though.
